This film has an antimicrobial protective layer. This helps to kill bacteria and fungal spores that get on the glass during daily use. The film is coated with an antimicrobial agent that is harmless to humans or the skin. As an additional feature, this film has a blue light protection layer. This ensures that your eyes are protected from the particular blue light emitted by our screens. This anti-blue light layer helps to soften the strong light from your phone, which is especially important in the darker hours before bedtime as the blue light can trick your brain into thinking it's daytime and disrupt your sleep patterns.
